STOVElPIPE-THIMBLE.

LDQTEIW.

Application filed September 10, 1912.

To all whom it may concern:

Be it known that I, Ennnsr E. MonLAN, a citizen of the United States, residing at C0- lumbia, in the county of Boone and State of Missouri, have invented a new and useful Stovepipe-Thimble, of which the following is a specification.

The invention relates to improvements in stove pipe thimbles,

The object of the present invention is to improve construction of stove pipe thimbles, and to provide a simple, inexpensive and efficient stove pipe thimble, designed to be permanently mounted in a chimney, and equipped with interiorly arranged means for limiting the inward movement of a stove pipe into the thimble and for securely connecting the stove pipe to the chimney to prevent the pipe from slipping or falling out of the thimble.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim here to appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing: Figure 1 is a vertical longitudinal sectional view of a portion of a stove pipe and a chimney, equipped with a stove pipe thimble, constructed in accordance with this invention. Fig. 2 is a perspective view of a stove pipe thimble. Fig. 3 is a similar view, illustrating another form of stove pipe thimble, the latter being open. Fig. 4 is a longitudinal sectional view of the stove pipe thimble, illustrated in Fig 3 and shown closed. Fig. 5 is a longitudinal sectional view of a stove pipe thimble, illustrating another form of the anchor. Fig. 6 is a detail perspective view of one of the anchors shown in Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a stove pipe thimble consisting of a block of plastic material, such as concrete, cement, or the like, and having a square exterior in order that it may be easily set in position in a chimney and have $pecification of Letters Patent.

the bricks thereof built around it. The plastic block is provided in its top, bottom and side faces with a central groove 2 and indentations 3, located in advance and in rear of the groove. The groove is adapted to receive mortar or cement, and the indentations provide roughened surfaces and are adapted to receive mortar or cement for retaining the plastic thimble in position in the wall 4 of a chimney. A single continuous centrally arranged groove 2 is provided, but the groove may be arranged at any other desired point and any number of grooves may, of course, be employed.

The plastic thimble is provided with a central circular stove pipe opening 5 and is recessed at the inner portion of the bottom thereof to provide a groove or channel 6 ha W ing an inclined bottom 7, adapted to cause any water accumulating in the thimble to drain back into the chimney. This will prevent the water from running through the thimble and soiling wall paper or other wall covering.

The front or outer portion of the opening 5 is cylindrical to receive the inner end section 8 of the horizontal portion of a stove pipe, and the said thimble is equipped at the top and bottom of the opening 53 with anchors 9, embedded in the plastic material and consisting of an outer horizontal portion 10, a vertical abutment or connecting portion 11 and ahead or enlargement 12, embedded in the thimble and preferably formed by arms projecting in opposite direc tions from the vertical connecting portion or neck 11. The arms of the head form a substantially T-shaped inner portion, and the horizontal portion 10 provides a substantially lL-shaped outer projecting portion. The horizontal portion ll.) of each anchor is arranged in spaced relation with the attached portion of the wall of the opening of the thimble, and the inner end of the stove pipe section 8 abuts against the vertical portion 11 of the upper and lower anchors, and the exterior horizontal attaching portions 10 project forwardly in a direction longitudinally of the stove pipe section 8 and extending into the same and are provided with perforations 13 and have wires 1st and 15 se cured to them preferably by being passed through the perforations l3 and twisted beyond the same, but any other suitable attaching means may, of course, be employed. The upper wire '14 extends through the hori-- zontal portion of the stove pipe and has its outer terminal bent to form a hook 1G for engaging the outer stove pipe section 17 ot' the said horizontal portion, and the lower wire 15 is preferably extended through the elbow 1S and has its lower terminal bent to term a hook 19 for engaging the lower edge of the said elbow. Instead, however, of

forming the hooks 16 and 19, as shown, the

outer ends of the wires may be secured to the stove pipe sections, as described in an application filed by me July 19, 1912, Serial No. 710,520, or by any other suitable means. By this construction, the horizontal portion of the stove pipe and the elbow are securely connected to the chimney and are prevented from falling out of the same.

As illustrated in Figs. 3 to 5 inclusive of the drawing, stove pipe thimbles may be constructed of sheet metal to enable them to be economically shipped, and in order that they may be nested in compact form, the sheet metal stove pipe thimble 20 is split longitudinally and provided at the longitudinal edges with alternately arranged spaced projecting tongues 21 forming recesses 22 at each longitudinal edge to receive the tongues of the other longitudinal edge. hen the thimble is bent into cylindrical form, the tongues 21 of both longitudinal edges extend through the recesses 22 and are arranged on the exterior or" the metallic thimble. The longitudinal edges fit together to form a smooth interior and the exteriorly arranged tongues 21 are adapted to be embedded in the mortar or cement of the chimney and assist in retaining the thimble in place. The inner end of the thimble 20 is provided with a flaring flange 23, which assists in retaining the thimble in a chimney, and the sheet metal thimble is also provided with an eXteriorly arranged annular groove 2a, which serves the double purpose of receiving mortar or cement for securing it to the wall of a chimney and also as an interiorly arranged stop for preventing water from fiowin through the thimble from the interior of the chimney to the exterior thereor". The sheet metal thimble is also provided at its upper and lower portions with anchors 25, located in advance of the groove 2% and constructed of suitable metal and secured by rivets 26, or other suitable fastening devices to the top and bottom of the thimble at the inner face thereof. Each of the anchor pieces consists of a horizontal portion, arranged in spaced relation with the inner face oi the thimble and connected by a neck portion 27 with an attaching portion or head 28. Each of the anchors 25 is provided in its spaced horizontal portion with a perforation 29 for the attachment of a wire for securing the stove pipe to the thimble in the manner heretofore described.

Instead of employing separate anchor pieces, integral anchors 30 may be employed, as illustrated in Fig. 5 of the drawing. The anchors 30, which are located at the top and bottom of the thimble 31, are formed by cut ting horizontal tongues or portions and bending the same inwardly to form the, horizontal portions and the connecting portions. Each of the anchors 30 is provided with a perforation S2 for the attachment of stove pipe wires.

\Vhat is claimed is A stove pipe thimble having a stove pipe opening and provided at a point intermediate of its ends with an interior anchor comprising a transverse abutting portion projecting from the W1 ll of the stove pipe opening and forming a stop for the inner end of a stove pipe, and a forwardly extending attaching portion disposed longitudinally of the thimble spaced from the said wall of the opening of the thimble and arranged to project into the inner end of the stove pipe, and a flexible connection secured to the said attaching portion at a point in advance of the abutting portion of the anchor and adapted to extend through the stove pipe and be secured to the same for connecting the stove pipe with the thimble.

In testimony, that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
